ANTl-RATTLER FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 369,427, dated September 6, 1887.

Application filed March 18, 1887. Serial No. 231,354. (No model.)

To aZZ whom, it may concern.-

Be it known that I, SAMUEL J. BINGHAM, of Binghamton, in the county of Broomc and State of New York, have invented certain new and useful Improvements in Anti-Rattlers for Thin-Couplings, of which the following is a description, reference being bad to the accompanying drawings, forming a part of this specification, in which- Figure l is a side view, in detail, of a portion of a buggyshaft, showing the usual shafteye and axle-clip to which my improved attachment is applied. Fig. 2 is a perspective view,in detail,of the compressing frame,block, and friction face-plate; and Fig. 3 is aside view of the same, the frame being shown in transverse section.

Like letters of reference indicate like parts in the different figures.

In devices heretofore in use in connection with thill-coupli'ngs for the prevention of the rattling of the thills it has been found that the rubber blocks soon expand laterally and become permanently flattened, thereby failing to exert the necessary elastic pressure against the shaft-eye. Moreover, it has been found objectionable to pass a bolt through the rub bcr block for the purpose of compressing it.

The object of my invention is to overcome these objections and to provide means whereby the lateral expansion of the rubber may be prevented, while a metallic frictionsurface may be provided to receive the wear of the shafteye and to form a bearing-surface for the screw by which the compression is produced, all of which I accomplish substantially in the manner hereinafter more particularly described and claimed.

A in the drawings represents a carriageaxle; i, the axle-clip; G, the shaft; and G, the shaft-eye secured to the eye 13' of the clip in the usual manner by means of a bolt, D.

E represents a hollow metallic frame cast from malleable iron or other suitable material, and ofsueh size as to be readily interposed in the space between the face B of the clip and the rounded surface of the shaft-eye. A portion, E, of the respective sides of said frame is cut away to conform to the curve of said shafteyc. lVithin said frame I place a compression-block, F, of rubber,of sufficient size to fill or substantially fill said frame, and the space between the clip'face B and the eye 0, the front face of said block being preferably con cave, ably of heavy tin,bent to lit the top and front, respectively, of said compression-block, is then placed against the same and normally secured in position by means of a screw, E". The frame E, with the compression-block and facing, is then placed in position between the clip and shaft-eye, as shown in Fig. 1, when, upon turning the screw 13*, the block]? is com pressed, and as the frame E prevents its lateral expansion, it presses against the shafteye, the interposed plate G serving as a frictional bearing-surface for the screw and shafteye.

This construction is wholly effective in preventing the rattling of the thill, while it is much more durable than the forms heretofore employed.

1 am aware that it is old to insert a compressioublock within a case which covers the top, bottom, sides, and back thereof,a follower plate and screw being employed to compress the block, which has its cut-out portion arranged to bear directly against the thill-eye. I am also aware that the yoke of the clip has been extended forward beneath the clip to form a support for awedge-hlocl: havinga' concave inner surface, between which and the thill-eye is inserted a compression-block faced with metal, the compression being accomplished by means of a setscrew in the yoke; but I do not claim either of said constructions.

What Ido clainnand desire to secure by Letters Patent, is

An anti-rattler for thill couplings, consisting of the elastic compressioublock F,in combination with the frame 13, plate G, and setscrew e,said plate covering the top of the compression-bloek to form a bearing for the setscrew, and being bent over the front of said as shown. A metallic facing, G, preferblock to form a friction bearingsurface, all of 95 said parts being constructed and arranged as described, and for the purposes specified.
